The Sun pulls on everything, so flying there should be easy... right? Not quite. Earth races around the Sun at about 30 km/s, and anything we launch keeps that speed, so it swings around the Sun instead of falling in. To reach the Sun, you have to lose most of that speed. NASA's Parker Solar Probe needed a huge rocket and seven trips past Venus to do it. https://www.youtube.com/embed/nb_n8czmGtA 27 2026-10-29T11:04:25Z yes https://www.fluffyfacts.com/shorts/one-spin-of-venus-takes-longer-than-its-year/ 2026-11-01T19:44:19Z https://www.fluffyfacts.com/assets/covers/one-spin-of-venus-takes-longer-than-its-year.e520c6dae8.jpg One spin of Venus takes longer than its year A spin sounds quick, but one spin of Venus takes about 243 Earth days. One trip around the Sun takes only about 225, so a Venus year is over before Venus finishes a single spin. Venus also spins backwards, so the Sun rises in the west. Sunrise to sunrise is a different story: about 117 Earth days, which is shorter than a Venus year. https://www.youtube.com/embed/DdiQN8R2h4Y 24 2026-10-29T16:44:19Z yes https://www.fluffyfacts.com/shorts/why-do-astronauts-grow-taller-in-space/ 2026-11-01T19:44:19Z https://www.fluffyfacts.com/assets/covers/why-do-astronauts-grow-taller-in-space.ad0bb9ae35.jpg Why do astronauts grow taller in space? Astronauts can grow up to 3% taller in space, roughly 5 cm (2 inches). On Earth, gravity squashes your spine a little all day; in orbit nothing presses down, so the spine stretches out. Back on Earth, gravity squishes astronauts back to their normal height. Scientists are still studying how much of that stretch comes from the soft discs between the bones. https://www.youtube.com/embed/jbyrofr8CNg 24 2026-10-29T16:44:24Z yes https://www.fluffyfacts.com/shorts/can-you-hear-anything-in-space/ 2026-11-01T19:44:19Z https://www.fluffyfacts.com/assets/covers/can-you-hear-anything-in-space.ce82e7a6d1.jpg Can you hear anything in space? Sound needs something to travel through, like air, and space is almost empty, so astronauts talk by radio. But in the Perseus galaxy cluster, a black hole sends pressure waves through hot gas. NASA's Chandra X-ray Observatory found they form a B-flat about 57 octaves below middle C, far too deep for any ear. In 2022, NASA scaled the waves up by 57 and 58 octaves so we can finally hear them. https://www.youtube.com/embed/CkX7l1m2e0w 27 2026-10-29T16:44:29Z yes https://www.fluffyfacts.com/shorts/why-do-we-always-see-the-same-side-of-the-moon/ 2026-11-01T19:44:19Z https://www.fluffyfacts.com/assets/covers/why-do-we-always-see-the-same-side-of-the-moon.ba5b49c45f.jpg Why do we always see the same side of the Moon? The Moon always shows us the same face, so it can't be spinning... right? It is: the Moon spins exactly once per trip around Earth (about 27 days), so the same side keeps facing us. Long ago it spun faster, until Earth's gravity worked like a brake and the spin matched the orbit (tidal locking). A slight wobble even lets us see about 59% of the surface over time. https://www.youtube.com/embed/WjqZY8yFhCw 25 2026-10-30T17:00:22Z yes https://www.fluffyfacts.com/shorts/the-first-animals-in-space-werent-dogs/ 2026-11-01T19:44:19Z https://www.fluffyfacts.com/assets/covers/the-first-animals-in-space-werent-dogs.c575183dcc.jpg The first animals in space weren't dogs Sef is sure the first animal in space was a dog. It wasn't even close. On 20 February 1947, a V-2 rocket launched from White Sands, New Mexico, carried fruit flies more than 100 km up, past the edge of space, and their capsule floated back down by parachute with the flies alive. And the first cat in space? Félicette, launched by France on 18 October 1963. https://www.youtube.com/embed/b_QcbN8-tAU 28 2026-10-31T17:00:08Z yes https://www.fluffyfacts.com/shorts/why-is-mars-red-its-not-the-heat/ 2026-11-02T17:07:48Z https://www.fluffyfacts.com/assets/covers/why-is-mars-red-its-not-the-heat.bd09200c44.jpg Why is Mars red? It's not the heat Mars looks red, but it isn't hot: it's a cold desert world. The red is rust, because iron in its rocks and dust has oxidized, and winds spread that dust all over the planet. A 2025 study suggests the main red mineral is ferrihydrite, which forms in cool water, so Mars may have rusted long ago while it still had water. Scientists hope to confirm this when samples from Mars come back to Earth. https://www.youtube.com/embed/8pGzXlnuL_Y 25 2026-11-01T17:00:10Z yes https://www.fluffyfacts.com/shorts/why-do-astronauts-see-16-sunrises-a-day/ 2026-11-02T17:32:58Z https://www.fluffyfacts.com/assets/covers/why-do-astronauts-see-16-sunrises-a-day.f1bc820aba.jpg Why do astronauts see 16 sunrises a day? The Sun isn't on fast-forward: the International Space Station circles Earth about every 90 minutes, at roughly 8 km (5 miles) every second. Each lap it flies through Earth's shadow and back into sunlight, so the crew sees about 16 sunrises and 16 sunsets a day. To keep a normal rhythm, astronauts live on a 24-hour schedule set to GMT, and some wear sleep masks to block the light. https://www.youtube.com/embed/ZAkp75O2S6c 29 2026-11-02T17:00:09Z yes https://www.fluffyfacts.com/about 2026-11-01T19:44:19Z https://www.fluffyfacts.com/privacy 2026-11-01T19:44:19Z https://www.fluffyfacts.com/data-deletion 2026-11-01T19:44:19Z https://www.fluffyfacts.com/contact 2026-11-01T19:44:19Z
